4 moles of nitrogen monoxide gas used to form 72.0 grams of water vapor.

<h3>What is a mole ?</h3>

A mole is the measurement unit which is used to correlate the molar mass with number of molecules present.

The equation for reaction of Nitrogen monoxide to form water vapor is given by

4NH₃ + 6NO ----> 5N₂ + 6H₂O

72 grams of water vapor means = 72/18 = 4 mole of water vapour

The mole fraction of NO to H₂O is 6 : 6

Therefore for 4 moles of water vapor formation , 4 moles of nitrogen monoxide will be required.

Element c has a strong emmission aound 450nm Does this emmission line reprosent a lower of higher emergy line at 627 nm?
Julli [10]

It  respresents the higher energy level than 627nm .

<h3>What is a emission line ? </h3>

Emission lines are the glowing hot gas emits lines of light whereas absorption line  refers to the tendency of  cool atmospheric gas to absorb the same line of light.Some lights produce dark band when the light passes through gas in the atmosphere . There are two line spectrum  and absorption.

 spectrum is an excitement of  electrons from lower to higher energy levels and when it comes back it releases energy in the terms of colourful lights .

It represents the  higher energy levels than 627nm because Energy is inversly proportional to wavelength .
